Reviewers Didn't Like
- Much more difficult
- Seemingly constant flow of enemies
- Less pacing control means less tension
- Bots have not really improved, they still cannot pick up explosives and have slow reaction times
- Some levels can be lengthy and frustrating if your team wipes
- PC version had/has a glitch that eats your Steam Achievements
- Slightly higher difficulty causes some frustration in the beginning
- AI teammates can be frustrating
